Dielectric absorption ratio
Updated 2026-10-27
Data records
- On an insulation resistance tester with timed modes the two time points for the dielectric absorption ratio are user-selectable and the instrument reports the ratio itself. The test is quick, is regarded as largely independent of temperature and shows up damp or contaminated insulation, but it is not suited to insulating oils.
